Kpplieation filed March 12, 1897.

To all whom it may concern:

Be it known that I, WILLIAM W. GREEN, a citizen of the United States, residing at Fort Dodge, in the county of Webster and State of Iowa, have invented certain new and useful Improvements in Machines for Punching Eyelet-Holes in Boot and Shoe Uppers; and I do hereby declare the following to be a f nll, clear, I and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improved machine for punching eyelet holes in boot and shoe uppers. i

The invention has for. its objects to provide novel punch mechanism for simultaneously punching the entire series. of eyelet-holes inone-half of an upper at one operation, to provide means for. adjusting the punches toward or from each other to operate upon difierent sizes or lengths of uppers, to further provide angular line of curvature andadapt them to operate upon difierent widths of uppers, and, finally, to improve and simplify the construction and render more efficient the operation of this class of machinery generally.

' To these ends the invention consists in the features and in the constructiomcombination, and arrangement of parts hereinafter more fully described, and set forthin the appended claims, reference being had to the accompa nying drawings, forming a part of this specification, in which- Figure 1 is a perspective view of my improved punching-machine, a portion of the frame and die-block being broken away to expose the stripper-plate. Fig. 2 is a top plan View of the pivoted punch-jaw and punchoperating mechanism. Fig. 3 is a detailed perspective view of the central punch-lever and connection s. Fig. 4 is a longitudinal sec tion of the pivoted punch-jaw on the line of one of the punch-levers. Fig. 5 is a top plan viewof the stripper-plate and adjustable gageplate. Fig. 6 is a vertical longitudinal section of the entire machine. Fig. 7 is a detailed perspective view of the end punch C and the springgage stud and shows in dotted lines the outer end ofpunch-lever Figs. 8, 9, and 10 said plate.

swarm). 628,156. (NomodeL) and Fig. 11 is a diagrammatic view showing" in full and broken lines upper halves of different sizes and widths.

Referring now more particularly to the said drawings, 1 represents the frame of the machine, consisting of the base 2, the side standards 3, and the'inclined fixed platen 4. Below this platen is a vertically-tilting support or punch-jaw 5, fulcrumed at its inner end on a transverse shaft 6, mounted in cars 7, formed integrally with the standards 3. The free end of the punch-jaw is mounted to tilt upon two toggle-jointed leaves 8 8, the said leaf 8 being pivoted at itsupper end to a transverse rod 9, fixed in cars 10 on the jaw 5, and the lower end of the leaf 8 on a similar rod 12, fixed in ears 13 on the base 2. At their meeting ends or edges the leaves are jointed by a pintle rod or shaft 14:.

The forward end of a connecting-rod 15 is pivoted to the rod or shaft 14, and the rear end of said rod is pivotally connected to a crank-pin 16, carried by the hub 17 of a gearwheel 18, rigidly mounted on a shaft 19, journaled inthe frame 1. A drive-shaft 20, also journaled in the frame, carries a band-wheel 21 and a pinion 22, which meshes with the said'gear wheel 18. The manner in which the punch-jaw is tilted bythe mechanism just described will be readily understood.

The support or tilting jaw carries on its up per face a bed-plate 26, secured thereto by screws-27, and on this plate the punch-carrying and adjusting mechanism is mounted. I will first proceed .to describe said adjusting mechanism and then the construction, arrangement, and mode of operation of the punch-levers and punches.

On the plate 26 is a transverse arm 23, provided with slots 24 for passage ofv screws 25, whereby it is secured to and fitted to slide on The outer end of the arm projects laterally at one side of the jaw and is provided with a, curved rack 28. Located above the arm is an adjusting-lever 29, havby a screw 31. The outer end of the levcr is I 37, projecting from the jaw 5, andadjacent thereto the lever is also pivoted to the trans "erse arm by the screw 38. The free end of said lever projects outwardly at the front of the jaw and carries a thumb-lever 39, having a pawl 40, adapted to engage the notches 41 of the rack 42.

Located at the rear end and to the left of the center of the jaw is a sliding plate or bar 43, which is pivoted at its inner end to the outer or rear end of the head by the screw 44, and formed at its outer end with a longitudinal slot 45, through which a pivot-screw 46 passes. This baris adapted to slide transversely of. the plate 26 to the extent of the length of the slot- 45. A similar sliding plate or 'bar 47 is located to the right of the center vof'the jaw in front of and parallel with the transverse arm23, and is pivoted at its inner end to the inner or front end of the T-shaped head 30 by a screw 48, and provided at its outer end with a longitudinal slot 49, through which apivot-screw 50 passes and enters the plate 26. This bar is also adapted to slide transversely of the plate 26 to an extent limited by slot 49. Two sets or series of curved punch-levers are pivoted to said plates 'or bars to move simultaneouslyor in unison. The levers 51 of one set are eachprovided with a slot '52 for passage of a f ulcrum-screw 53, and the inner ends of theselevers are pivotedto thesliding bar 43 by screws54. The levers 55 of the other set are provided with similar slots 56 for passage of fulcrum-screws 57 and have their inner ends pivoted to the bar 47 by screws 58. These screws 53 58 enter the bed-plate 26. Each lever 51 55 is formed at its outer end with an open end slot or bifurcation 59, which .receives the collar 61 of a tubular punch 62. The said collar 01 of each punch is preferably formed with a groove or recess to receive Men.

the edge of one of the arms of the bifurca- By this construction independent rotative movement of the punch is prevented, while provision is made for readily and con- Veniently sliding it out of the slot and disengaging it from the punch-lever.

A central punclrlever a is arranged between the two sets of punch-levers 51 55and is pivoted at its inn-er endto the transverse arm 23 by the screw 31. This lever is formed with a slot a for passage of a fulcrum-screw a which enters the plate 26 and at its outer end with a slot or bifurcation 59', corresponding to the slots 59 of the other levers. The function of this central lever will be hereinafter described. The pivotal points of the levers of each set 5] 55 are arranged in a- This lever 35 is pro-- curved line or in the arc of a circle, begin- 11in g with the innermost lever and extending outwardly and rearwardly therefrom. In other words, the fulcrum-screws of the several levers are located at different distances from their outer ends, from the screw of the innermost lever, which is the nearest, to the screw of the outermost lever, which is the farthest, the screw of each lever being arranged a step fartherback in regular order or progression. By this 4 construction the outer ends of the levers of both sets, when adjusted toward the central lever a, move closer together or toward each other and when adjusted in the reverse direction spread apart or move from each other. The extent of throw of each lever may be regulated by changing the position of the fulcrum-screw in its slot.

For convenience in explaining the mode of operation of the punches those punches carried by the levers 51 are designated 1) b b b b b b b" and those carried by the levers 55 c c c c 0 In operation the latter-named punches form the eyelet-holes at the upper portion of the upper and the former the eyelet-holes at the-lower portion of the upper. The central punch-lever carries a punch a, which forms an intermediate punch-hole from which the others graduate in different sizes and lengths of upper halves, as will appear more fully hereinafter.

The bed-plate 26 consists of two sections, a rear section 26', secured, as before stated, by the screws 27 to the punch-jaw, and a detachable front section 26 secured by thumbscrews 11, projecting up through the punchjawand entering threaded orifices in its un der side, as shown in Fig. 4. The inner edges of these two sections are spaced apart and curved to form between them an angularly or irregularly curved guide-slot 63, in which'the base portions of the collars 61 of ,the punches are adaptedto fit and slide, as shown. in said .figure. This slot is made to conform as nearly as possible to the curvature of the meeting edges of upper halves of difierent sizes and widths, the different adjustments being secured by moving the punches in said slot.

The punches are supported and guided by guard-plates 64 64, secured, respectively, to the bed-plate sections 26 26 by screws 65. By releasing the thumb-screws b from engagement with said bed-plate section 26 the latter, together with the guard-plate 64', m'ay be detached to permit of all or only a "portion or" the number of punches as desired being disengaged froin the punch-levers. The machine may thereby be quickly set to work upon the upper halves of low-quarter shoes or to leave an un punched space at the upper portions of upper halves of ordinary high shoes for the reception of lace-fasteners which do not require eyelet-holes.

The f u nctionof the lever 29 is to adjust the punches toward or from each other to operate upon difierent lengths or sizes of uppers 2, 2-5, 3, 3%, 4, &c., and that of the lever 35 to adj ustTthe punches to vary their line of curvature to operateupon dilferent widths of uppers-namely, A, B, C, &c. Fig. 8 shows the punches adjusted close together or toward each other for operating upon small-sized uppers, and Fig. 9 shows the punches spread apart for operating upon uppers of larger size.

The proportions of the parts in these figures are somewhat exaggerated in order to clearly disclose the effect of the different movements. The necessity for these different ad justmcn ts will be understood by reference to Fig. 11.

This figure shows in full lines an upper half of size '7, width A, in short dotted lines an upper half of size 7, width E, and in alternate long and short broken lines an upper half of size 4, width A. The positionspf the eyeletholes punched in each upper are also shown. These uppers are represented, respectively, by the reference letters \Y'X Y. u 21* designate the upper and lower edges or ends of the upper XV, .r' the upper and lower ends or edges of upper X, and 1 the corresponding ends or edges of upper Y. The uppers are represented as placed with their upper edges and upper portions of their meeting edges in alinement, and it will be noted that their inner side or meeting edges are ofsubstantially the same shape or contour down to the point .2. The lower portions of the uppers from this point, however, vary in line of curvature down to their lower ends in y .2".

This. variation exists to a greater or less extent in the several widths from A to E, and in order to accommodate the punehesto operate upon thesedifferent widths their angular line of curvature must be varied by adjusting them together or in a body in the curved slot 63. As an example, in a full-sized machine the punch (:1 carried by lever of set 55, in order to punch width A must be located five-sixteenths of an inch farther to the left,

measuring from an y certain point, such as the end'of the guide-slot, than to punch width E,

while at the same time the punch b carried by the corresponding lever of set 51, in order to punch width A must be located five-eighths of an inch farther to the left than to punch width E. r

The eyelet-hole .2" in each upper opposite the point e is formed by the punch a carried by the central punch-levera, the eyeletholes below the same or at the lower portion of the upper by the punches Z) Z) 11 &c., and the eyelet-holes above or at the upper por tion of the upper by the punches c 0' 0 &c. It will be seen that this eyelet-hole z is located at approximately the same distance from the upper edge of the uppers W and Y,

although they are of different sizes, but that per and lower edges.

the remaining punch-holes are spaced farther understood that the-punches carried by the sets of levers 5155 are moved toward or from each other and toward or from the punch carried by lever ain adjusting them to operate upon different sizes or lengths of work. When the lever 29 is moved inwardly or toward the rear of plate 26, as shown in Fig. 8, the free ends of the punch-levers 51, through the medium of bar 43, are moved toward the right, and thefree ends of levers 55, through the medium of bar 47, are moved toward the left,thus bringing the punches closer together. Upon the said hand-lever 29 being moved outwardly, as shown in Fig. 9, the punchlevers are'adjusted in the reverse direction and the punches spread apart. The central puneh-lever .a, it will be noted, is not connected with the hand-lever 29, and therefore remains stationary when saidhand-lever is moved and serves as a fixed point toward or from which all the levers 51 ,55 are adjusted. To this is due the substantially-coinciding positionsof the punch-holes .2" in the uppers WV X Y.

When the lever 35 is moved outwardly or to the right, as shown in Fig. 10, it carries with it the transverse arm 23 and sliding bars 43 -17. This movement of the sliding bars to the right causes all of the punch-levers, in-

.cluding the central lever a, to turn on their fulcrums,the screws 52 57 airespectivel gand the free ends thereof carrying the punches to move toward-the left. The position of the punches as a whole in the slot 63'is thereby change and their line ofcurvature varied. It will be understood that this variation in the line of curvature is effected by the change in position of thepunches 1) H0 850., carried by the lovers 51 at the inwardly and out-- \vardly curved portion of the slot at the lefthand end, the line'of curvature of the remaining punches being substantially the same in all the adjustments for widths. It follows, therefore, that provision is made for adjusting those punches which form the punchholes at the lower portions-of uppers, which vary in line of curvature in different widths and for maintaining the proper line of curvature of those punches which form the punchholes at the upper portions of uppers, which upper portions are substantially the same in line of curvature in all widths, as clearly illustrated in 11. By moving the lever 35 inwardly the parts are adjusted in the reverse direction; e e

. The distance between the end punches If 0 remains approximately the same in punch-- ing all widths of uppers of a given size. In

' adjusting the punches by lever 35, however,

they nioveto a slight extent toward or from each other, according to the direction in which they are adjusted, but to a less extent than when adjusted by lever 29.

. It will be apparent from the above description that the punches when adjusted to operate upon diiferent sizes or lengths of work move toward or from each other, but when adjusted to operate upon. different widths of work of a given size change their position as a whole to vary their angular line of curvature in the slot 63.

it stripping-plate 67, which serves as a guide, is fixed to the frame above the punchjaw and is provided near its front end with a sinuous or irregularly-curved slot 68, through which the punch-tubes move. 69 represents a spring gage-pin sliding in a barrel 70,mount ed upon an ear or extension 71, formed on the outer side of the curved lever 55. This pin projects through the slot 68 in the stripper-plate and forms a gage for the top of the upper to locate the series of eyelet-holes, so that the first eyelet-hole will always be the same distance from the top edge of the upper no matter in what position the punches may be adjusted. On the stripping-plate is i a curved gage-plate 72, against which the meeting edge of the upper rests. This gageplate is pivoted at one end and provided with a central slot 73, through which a screw 74 passes and secures it to the stripping-plate. In order to adjust. the gage-plate, I provide a shaft 75, journaled in bearings 76 and having at its outer end a milled head 77, by means of which it may be conveniently manipulated. The shaft carries a pinion 7 8, which engages a rack 79 on the gage-plate. By adjusting the gage-plate the location of the eyelet-holes may be varied relatively to the edge of the upper.

The fixed platen 4 carries a die-block 80, which fits in a recess 81 in its under side and is held by means of set-screws 82. This block may be removed to expose either of its faces on to substitute a new'block therefor by releasing said screws 82.

In operation the upper is laid upon the stripping-plate with its upper edge abutting against the spring gage-pin 67 and its meeting edge abutting against the gage-plate 72, and then the punch-jaw 5 is tilted to force the punches through the upper and against the die-block. The cuttings drop through the punches and slots in the bed-plate and punch-jaw to the floor or ground.

From the foregoing description it will be seen that the adjustment of the punches is very sensitive and varied. These punches are simultaneously movable inwardly toward or outwardly from each other to compensate for a difference in sizes of uppers or to place the eyelet-holes closer together or farther apart within the same size. In their movement the punches are guided in a curved slot having a partial contour differing from a continuouso'r regular arc of a circle and thereby are caused to accommodate upper sections having an irregular curved edge line adjacent to which the said eyelet-holes are to be punched.

Although I have specifically described the construction and relative arrangement of the several elements of my invention, I do not desire to be confined to the same, as such changes or modifications may be made as clearly fall within the scope of the invention without departing from the spirit thereof.

Having thus fully described my invention,
